Abstract: 966,993. Catalytic reactions. BADGER CO. Inc. March 1, 1961 [March 3, 1960], No. 7442/61. Heading B1F.   In carrying out a vapour-phase fluidized-bed catalytic reaction, a stream containing reactant vapours is successively passed upwards through (a) a first dense-phase bed 14 of catalyst particles maintained in a turbulent fluidized state while controlling the temperature within this bed to promote the reaction, (b) a dilute-phase bed 26, (c) a second dense-phase bed of catalyst 28 while controlling the temperature within this bed to have a value below that in 14. The catalyst in 28 is removed and returned to 14 when 28 exceeds a predetermined depth using a pipe 42 which is made operative in one direction only with baffle 44, i.e. for transferring catalyst from 28 to 14. A means of controlling the temperature in both dense-phase beds is provided in the coils 24 and 32. The aerial oxidation of naphthalene or o-xylene to phthalic anhydride using vanadium pentoxide as catalyst is described.

At each end of its travel the member 22 is thrown over by a ball 25 engaging spring- controlled pawls 44, 53, respectively mounted on carriers 36, 47 slidable on a pair of rods 31, 32. The carriers carry respective bolts 39, 48 having clamping nuts for adjustment by means of pointers 37, 50. When the member 22 is moved to the left, the cam-like part 30.of a blade 28 thereon engages a pin 63 and moves a pivoted contact 58 on to a contact 57. At a time-interval depending on the adjustment of carrier 47, the pawl 53 throws over member 22 for reverse movement but the contacts 57, 58 only open when, during this reverse movement, pin 63 rides off the step 29 of blade 28 and remain open until the member 22 has been to the far end and back. A spring plate 26 on the part 21 carries a nut 27 engaging recesses in member 22 to hold it in its operative positions. The contacts close the circuit of solenoid 64 which may be the solenoid 36 of Specification 514,176, [Group XXV], in which, during energization, application of zipfastener elements to a carrier is interrupted. The spindles may be grooved for engagement by pins on member 22, which may control the cyclical operations mechanically through linkage instead of by the switch shown.

The mineral base material may be sand, washed limestone, marble, or dolomite, part of the base material consisting of a powdered mineral filler, e.g. chalk, the filler forming 2 to 6.5% by weight of base material.  Addition of a gel-forming substance, e.g. gelatin, or bentonite in a proportion of 1.5 to 3% of mortar, reduces the quantity of water necessary in making the mortar.ALSO:A finishing mortar for walls comprises a fine-grained mineral base material, a binding agent consisting of slaked lime and ethyl cellulose, and water.  The slaked lime, which may form 2,5 to 10,5 times the weight of ethyl cellulose is preferably dry-slaked, i.e. powder-lime.  The mineral base material may be sand, crushed limestone, marble, or dolomite, part of the base material consisting of a powdered mineral filler, e.g. chalk, the filler forming 2 to 6,5% by weight of base material.  Addition of a gel-forming substance, e.g. gelatin, or bentonite in a proportion of 1,5 to 3,0% of mortar, reduces the quantity of water necessary in making the mortar and assists its application to walls.  In two examples, proportions of crushed marble, chalk, powder-lime, ethyl cellulose, and water, with and without bentonite, are specified.  The mortar is prepared by making a solution of ethyl cellulose and a dispersion of gel-forming substance in separate vessels, adding them to a mixer, and then adding other solid constituents and remaining water either immediately or subsequently, e.g. after 10 minutes, and mixing the whole.
